The Overseer science model

the engine that models the nutrient movements for that farm through a series of calculations, and

the reports which display the analysis for interpretation (and are stored in the database).

All three components work together to undertake scenario analyses of different nutrient outcomes for a farm to inform management decisions.

The engine is made up of a series of sub-models that calculate the flow of seven major farm nutrients – Nitrogen (N), Phosphorus (P), Potassium (K), Sulphur (S), Calcium (Ca), Magnesium (Mg), and Sodium (Na) and greenhouse gases.

What Overseer covers

The Overseer model has been expanded over time (see development history timeline) to cover a wide range of different farm enterprises and management practices in New Zealand. It can model mixed and single enterprise farms of varying intensity and with or without irrigation.

Educate agricultural science students (describing and understanding implications of nutrient management on New Zealand farms e.g. in agricultural qualifications at universities).

Software updates and version numbers

As with any software, Overseer is updated at regular intervals - to fix known problems, improve or add features and add new science. When updates are made to the science model, the model version number changes. The version number can be found on the top right of the farm analysis page in OverseerFM. The current version number is 6.3.0. The number format represents the scale of change

X

is the major version number. It only increases when there’s a major change to the design or structure of the model. The last update was in 2012, when Version 6 was released to include the urine patch model.

Y

is the minor version number. It increases when functionality changes are made, for example, new science or sobmodels are added. The last minor version change occurred in 2015, when the irrigation module was added.

Z

is the patch version number, and increases when minor changes are made, for example bug fixes.

Using Overseer results

Overseer adds value to farm management decisions because it predicts the outcomes of changes in farm management on nutrient loss. Because OVERSEER provides an individual analysis of a farm, it helps users identify the best ways to manage that farm and mitigate potential losses of nutrients into the environment.

The following summary identifies the farm management areas that have the most influence on nutrient loss estimates:

4. Using a Farm Account

a) Overview

A Farm Account represents a notional farming operation to be modelled in Overseer. To create a Farm Account, you will need to nominate a Farm Account Owner. A Farm Account Owner represents the farming operation being modelled.Each Farm Account must be used to model only a single farming operation. This may include the modelling of adjacent or additional land to the extent that it is relevant to nutrient and/or greenhouse gas modelling for that farming operation.

b) Access to a Farm Account

Your access to a Farm Account in Overseer is based on the Organisation your User Profile is associated with.An Organisation Administrator may invite users to join their Organisation. A Registered User accepting an invitation to join an Organisation will move from its current Organisation to the new Organisation.Farm Account Owners can grant or revoke access for Organisations to the Farm Account.Farm Account Administrators can grant access for Organisations to the Farm Account and revoke any access they have granted previously.These specific Farm Account Owner and Farm Account Administrator actions are available only to administrative users within the relevant Farm Account Owner and Farm Account Administrator Organisation.When an Organisation is granted access to a Farm Account, all Registered Users within that Organisation will have access to the Farm Account and be able to create Analyses and view, download, edit or remove any Analyses shared with that Farm Account.If you are granted access to a Farm Account by a Farm Account Owner or Farm Account Administrator, you accept their control of the Farm Account as outlined above.

c) If you are a Farm Account Owner

A Farm Account Owner can remove themselves from the Farm Account. If you do this, you acknowledge you will cease to have any rights in relation to the Farm Account.A Farm Account Owner can add or remove other Organisations as Farm Account Administrators. If you do this, keep in mind they will be able to grant access for other Organisations to the Farm Account as outlined in these terms.A Farm Account Owner can assign other Organisations as additional Farm Account Owners. If you do this, keep in mind they will be able to grant and revoke access for other Organisations to the Farm Account as outlined in these terms, and they will be able to remove other Farm Account Owners.These specific Farm Account Owner actions are available only to the Farm Account Owner.

d) Analyses

Year End Analyses are available to all Organisations who have access to the Farm Account.If you create a Scenario or Predictive Analyses, by default it is shared with your Organisation. You can share private Scenario or Predictive Analysis with the Farm Account Owner, or with all Organisations who have access to the Farm Account.If you publish an Analysis to an Organisation (including Regional Councils), a copy of that Analysis information is made available to that Organisation to view and download. You cannot change, reverse or withdraw that copy once published.Analyses are created by Registered Users for their own use. Unless otherwise agreed in writing, we accept no responsibility for any use of, or reliance on any Analysis by any other person. We will not be liable on any basis for any loss, damage or expense arising from that use or reliance.

e) Farm Account Data

If you enter, upload or share information to a Farm Account, you accept that from then on the information may be accessed and shared as defined in these terms of use. Once Registered Users have copied or downloaded information from a Farm Account, we do not control their subsequent use or sharing of that information.If a Farm Account is no longer used we may choose to delete that Farm Account and/or associated Farm Account Data.We can retain Farm Account Data indefinitely, but for so long as we do, we will continue to comply with the restrictions in this section and section 5.Our obligations relating to Farm Account Data are owed solely to the person or entity that controls the Organisation designated as Farm Account Owner.You agree that you cannot and will not restrict any Farm Account Owner’s use of their Farm Account(s), or their access to or sharing of Farm Account Data associated with their Farm Account. You also permanently waive any rights you may have outside these terms to impose or enforce any current or future restrictions of this kind on any Farm Account Owner. This section is for the benefit of the Farm Account Owner, and can be enforced against you by the Farm Account Owner as a third party beneficiary, although we can change this section without the need for the consent of any third party beneficiary. This does not affect any agreement to transfer a Farm Account as part of the sale and purchase of a farm or farming business.
